The game centers around the corruption and seduction of the women that you, the player, associate with over the course of a summer term working as a lab assistant.

Characters
You – A third year chemical engineering student, brought onto into the lab to help keep the equipment working.
Nora – The lab director. Science is her passion, and she runs her small lab with enthusiasm.
Stephanie – A graduate student and fellow lab assistant. She has been Nora’s right hand girl for years.
Mom – Your mother. Without your father she works long hours to make sure you and your sister can both earn a university education.
Lily – Your younger sister. She also goes to the same university for History, but unlike you has the summer off.
Alexia – A classmate from last semester. She seems to be interested in seeing you more over the summer.

Changelog for 0.11.0:
This update adds two major features to the game. The first is the new “Anal Lover” tag and a pile of new content to go along with it. There have also been modifications to any of the old pieces of anal content, making it much easier to reach if you have trained a girl appropriately.
The second major addition to the game is the ability for the girls to become pregnant. Each girl has an internal counter that is increased every time you finish inside her. The counter is increased by a significantly larger amount if you have enough influence over the girl to ask her to stop taking her birth control. Training a girl to be a public slut increases her pregnancy score as well (unless she has also been trained as an Anal Lover). It takes between 12 (no BC, public cumslut) and 100 (on BC) creampies for a girl to become pregnant.
There have been 6 new endings added to the game to reflect your ability to get girls pregnant. There is a solo pregnant ending for each girl, in addition to a pregnant harem ending that includes all five girls.
